Title: Mode changeover device of tape recorders
Inventor: KOBAYASHI MINORU
IPC: G11B15/18
Filed: 1978-04-20
Abstract: PURPOSE: To enable size to be reduced and operating member to be lightly moved in the mode changeover device of a tape recorder which is so arranged as to changeover the mode to recording mode by moving a single operating member in one direction and changing over the same to reproduction mode by moving the member to the other direction.  
     CONSTITUTION: When an operating button 3 is moved forward, an opeating member 16 moves forward integrally with this, causing a capstan shaft 40 to rotate clockwise. In cooperation to the forward movement of the operating member 16, idler pulleys 41, 42 move toward the left and the pulley 42 makes pressure contact to the reel base 46a on the left side, then the rotating force of the capstan shaft 40 is transmitted to the reel shaft 8a. Hence, the magnetic tape in a cassette having been set in the cassette leading part is sent in the left direction at the speed having been set by the capstan shaft 40 and is taken up on the reel of the left side by the revolution of the reel shaft 8a. As a magnetic head 24 makes slide contact to the tape, the specified recording operation is accomplished.

Title: Waveguide-microstrip line converter
Inventor: NODA MASAKI
IPC: H01P5/107
Filed: 1984-03-14
Abstract: PURPOSE:To decrease the skin effect of a wall face current by adhering closely a thin metallic plate with low loss to a supporting metallic plate cross section exposed to a waveguide wall so as to decrease the skin resistance of the waveguide wall. CONSTITUTION:A skin metallic plate 15 inserted between terminated rectangular waveguides split into two whose one end is placed between a supporting metallic plate 7 and a ground conductor 5 of a dielectric substrate 6 and whose other end is placed between the supporting metallic plates 7 is adhered closely to the supporting metallic plate 7. The type of material of the skin metallic plate 15 is a material with high conductivity and low loss, e.g., a copper plate having a thickness of 30mum. The skin resistance of the waveguide wall of the waveguide- microstrip line converter is decreased independently of the type of material of the supporting metallic plate 7 by using the skin metallic plate 15 so as to decrease the conversion loss. Then the waveguide-microstrip line converter with low conversion loss is obtained with inexpensive and simple constitution.

Title: Solid-state imaging device having contact pin
Inventor: MATSUSHITA TAKAICHI
IPC: H01L27/14
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To prevent poor contact or damage to the pattern of a contact part by allowing the connection tip part of a contact pin to be a flat surface, related to the connection part of a solid-state imaging device wherein connection is made by a tip part contact of the contact pin. SOLUTION: An electronic part 7 is placed on a connection part 2 of a solid- state imaging device, and an arm 9 pressurizes from above so that a contact pin 1 contacts, from below, a contact part 8 which is a pattern part of the electronic part 7 to be connected. Here, with a tip part 1a of the contact pin 1 of the flat connection part 2, the flat tip part 1a contacts the electronic part 7 for connection. Thus, the contact area to the contact part 8 is wider for better contact, suppressing such problem as poor contact. The plainer contact prevents damage to the contact part 8 of the electronic part 7.

Title: Circular polarizing antenna and radio device using same
Inventor: KUSHII YUUICHI
IPC: H05K1/18
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To make the antenna thin and to reduce the mount cost of components by mounting surface mounted antenna on a mount substrate so that their planes of polarization cross each other at right angles, and providing on the same mount surface an amplifying circuit, a shield case which covers it, and a phase circuit which feeds electricity with a specific phase difference. SOLUTION: The two surface mounted antennas 3 and 4 are arranged having the length directions f their base bodies crossed at right angles so that the planes of polarization of radiated radio waves cross each other at right angles in the normal direction of the mount substrate 2. The phase circuit 6, shifts the phases of signals supplied from the two surface mounted antennas 3 and 4 to the amplifying circuit by 90 deg.. Consequently, the circular polarizing antenna 1 operates as an antenna corresponding to a circular polarized radio wave. Consequently, the shield case containing the surface mounted antennas 3 and 4 and amplifying circuit and the phase circuit 6 can be mounted on only the other main surface of the mount substrate 2, so the mount substrate 2 which is inexpensive can be used to lower the mount cost of the components.

Abstract: PURPOSE:To lower noise to the extent of a vibration sound of a plate spring eliminating an impact member by mounting a permanent magnet piece to a plate spring retaining a wire to form a magnetic path in combination with a yoke and a core arranged contactlessly of an electromagnetic unit. CONSTITUTION:In an electromagnetic unit 6, a yoke 8 and a core arranged parallel along the direction of moving a wire 2 are integrated on a yoke base section 8a in the shape of roughly U viewed from the side and a coil 10 is wound on the core 9. When printing, a DC printing pulse is applied to the coil 10 so that a core head 11 will turn to an N pole and hence, the tip of the yoke 8 turns to the S pole. As a result, a magnetic flux with a permanent magnet piece 13 is cancelled during the non-energization time and energy accumulated in a plate spring 3 with the deflection thereof to the electromagnetic unit 6 during the non-energization time is released while a reaction acts on the permanent magnet piece 13 with the N pole of the core head 11 and the S pole of the yoke 8 and the plate spring 3 deflects elastically in the direction of printing. Thus, a printing action is done with the wire 2 retained on the plate spring 3.
